A method of performing a blockchain transaction on a blockchain, comprising: partitioning a private key of an account into a first part, a second part, and a third part, using a processor; delivering the first part to a user of the account via a network; storing the second part on a first server in association with information about the user; receiving the first part from the user via the network; generating a public/private key pair; encrypting the third part using the private key of the public/private key pair; storing the encrypted third part and the public key of the public/private key pair on a second server; converting the private key of the public/private key pair into a mnemonic; delivering the mnemonic to the user; receiving the mnemonic from the user; decrypting the third part using the mnemonic; reconstructing the private key of the account using the first part and the third part; and performing the blockchain transaction using the account and the reconstructed private key.
This invention relates to secure blockchain transaction methods that enhance privacy and security by partitioning a user's private key into multiple components stored across different locations. The problem addressed is the risk of unauthorized access to a user's private key, which could compromise blockchain transactions. The method involves splitting the private key into three parts: the first part is delivered to the user, the second part is stored on a first server linked to user information, and the third part is encrypted and stored on a second server. A public/private key pair is generated, and the third part is encrypted using the newly generated private key. The public key is stored alongside the encrypted third part. The private key of the new pair is converted into a mnemonic and provided to the user. When a transaction is initiated, the user submits the mnemonic, which is used to decrypt the third part. The first and third parts are then combined to reconstruct the original private key, enabling the blockchain transaction. This approach ensures that no single entity holds the complete private key, reducing the risk of theft or unauthorized access. The method leverages distributed storage and encryption to enhance security while maintaining usability.
2. The method of claim 1 , wherein the private key of the public/private key pair is converted to a mnemonic using an implementation of Bitcoin Improvement Protocol (BIP-39) protocol.
A method for cryptographic key management involves converting a private key of a public/private key pair into a mnemonic phrase using the Bitcoin Improvement Protocol (BIP-39).
